TOOL OF CONTINUOUS WIDE STRIP HOT ROLLING MILL Russian patent published in 2010 - IPC B21B27/02 

FIELD: technological processes.

SUBSTANCE: tool comprises working rolls with barrels installed in certain stand of mill, at the same time each barrel is arranged with curvilinear generatrix of its surface and has minimum diametre in the middle of its length, value of which depends on profile of rolled strip. Provision of required section of strips with optimal difference of thicknesses in the middle and at the edges of strip is delivered as a result of the fact that in order to roll strips of double width of its requied value, difference δ of maximum and minimum diametres of roller barrels in i stand of finishing group of mill is controlled by mathematical expression, which takes into account similar difference Δ of roller diametres of the same stand for rolling of strips of single width and parametres of strips cross section.

EFFECT: invention is intended to improved geometry of cross section of double-width hot-rolled strips intended for further slitting, due to appropriate profiling of working rolls in finishing stands of continuous wide-strip mill.
